The new video shows the Frenchman's Marussia car coming off the Suzuka track in rain-drenched conditions and ploughing into the back of a recovery tractor.

Also visible is an official in the top-right of the screen waving a green flag indicating to drivers they have passed a potential danger point.

The moment of impact

The sport's governing body, the FIA, had previously said yellow flags - which tell drivers to slow down and expect to stop - were being waved during the F1 race.

The full statement said: "On lap 42, Adrian Sutil lost control of his car, spun and hit the tyre barrier on the outside of Turn 7. The marshals displayed double waved yellow flags before the corner to warn drivers of the incident."

The Marussia driver remains in a critical but stable condition at the Mie General Medical Center suffering from a diffuse axonal injury, a joint statement by his family and the hospital announced on Tuesday.

Questions have been asked over whether it should have been stopped earlier.

Williams driver, Felipe Massa, said: "I was already screaming on the radio five laps before the safety car that there was too much water on the track, but they took a bit too long and it was dangerous."

An official FIA investigation into the incident is ongoing. They told the BBC: "This report is still under elaboration as it concerns the cross-checking of a number of different sources of information.

"It will aim to be as complete and detailed as possible in order to understand exactly the accident which occurred."
